Inga Hellige will research fast growing sea lettuce
Inga Hellige is a new postdoctoral researcher at the Department of Marine Sciences. She has a passion for macroalgae and will conduct research on the green macroalgae sea lettuce to contribute to the sustainable growth of seaweed farming in Europe. She is particularly interested in fast growing individuals and will investigate how easily they can be cultivated.
What will you be working on here?
“As part of the Blue Bio Boost project, I will be working with Ulva, a green seaweed called sea lettuce, that shows great promise as a future crop for sustainable aquaculture. My research will explore how different genetic types and changes in polyploidy influence Ulva’s shape, growth potential and morphological stability. I am especially interested in fast growing individuals, looking into how easily they can be cultivated, whether their “giant” traits can be passed on, and what their biochemical profile might offer for future applications. The goal is to support the development of advanced breeding strategies for seaweed and help drive the sustainable expansion of aquaculture in Europe.”
What did you do before?
“I completed my PhD at MARUM Centre for Environmental Research at University of Bremen and Max-Planck-Institute for Marine Microbiology, Bremen, Germany, as part of the Sea4SoCiety initiative within the CDRmare research mission. My research focused on assessing the carbon storage potential of brown macroalgae. These macroalgae pay a significant role in capturing atmospheric carbon dioxide, both by storing it in their biomass and by producing carbohydrates through photosynthesis.”
“A central part of my work was the analysis of dissolved sugars exuded by brown algae and their resistance to microbial degradation. Resistance may allow the sugars to assemble into aggregates that sink to the seafloor, contributing to long-term carbon sequestration. Carbon storage through macroalgae is most effective when paired with reforestation efforts and large-scale aquaculture. I am now excited to build on this experience by developing cultivation skills and deepening my knowledge on Ulva as a promising crop for future sustainable aquaculture.”
What do you do when you are not working?
“I enjoy spending time outside, going for a run, a hike or doing water sports. If you cannot find me outdoors, I will possibly paint or craft some artworks or bake cakes.”
Anything else you would like to share?
“I am looking forward to living and working at Tjärnö and continue my passion on working with macroalgae. I am excited to share my expertise as well as learn from my new colleagues here.”
